这是一款炫酷的鼠标hover图片幻影跟随动画特效。该特效在鼠标hover图片时,会产生多种颜色形成的堆叠卡片幻影,跟随图片移动,效果非常炫酷。
使用方法
HTML结构
该图片hover效果的HMLT结构如下:
<div class="grid grid--effect-vega"> <a href="#" class="grid__item grid__item--c1"> <div class="stack"> <div class="stack__deco"></div> <div class="stack__deco"></div> <div class="stack__deco"></div> <div class="stack__deco"></div> <div class="stack__figure"> <img class="stack__img" src="img/1.png" alt="Image"/> </div> </div> <div class="grid__item-caption"> <h3 class="grid__item-title">anaerobic</h3> <div class="column column--left"> <span class="column__text">Period</span> <span class="column__text">Subjects</span> <span class="column__text">Result</span> </div> <div class="column column--right"> <span class="column__text">2045</span> <span class="column__text">133456</span> <span class="column__text">Positive</span> </div> </div> </a> <a href="#" class="grid__item grid__item--c2"><!-- ... --></a> <a href="#" class="grid__item grid__item--c2"><!-- ... --></a> </div><!-- /grid -->
CSS样式
在CSS布局中使用flexbox进行布局,其中,堆叠的幻影图片的css样式如下:
.stack { position: relative; width: 100%; height: 200px; transform-style: preserve-3d; } .stack__deco { position: absolute; top: 0; left: 0; width: 100%; height: 100%; background-color: currentColor; transform-origin: 50% 100%; } .stack__deco:first-child { opacity: 0.2; } .stack__deco:nth-child(2) { opacity: 0.4; } .stack__deco:nth-child(3) { opacity: 0.6; } .stack__deco:nth-child(4) { opacity: 0.8; } .stack__figure { position: relative; display: flex; justify-content: center; align-items: center; overflow: hidden; width: 100%; height: 100%; cursor: pointer; transform-origin: 50% 100%; } .stack__img { position: relative; display: block; flex: none; }
JAVASCRIPT
特效中使用js来驱动动画效果,其中的一种效果的js代码如下:
HamalFx.prototype._in = function() { var self = this; this.DOM.stackItems.map(function(e, i) { e.style.opacity = i !== self.totalItems - 1 ? 0.2*i+0.2 : 1 }); anime({ targets: this.DOM.stackItems, duration: 1000, easing: 'easeOutExpo', translateY: function(target, index) { return -1*index*5; }, rotate: function(target, index, cnt) { if( index === cnt - 1 ) { return 0; } else { return index%2 ? (cnt-index)*1 : -1*(cnt-index)*1; } }, scale: function(target, index, cnt) { if( index === cnt - 1 ) { return 1; } else { return 1.05; } }, delay: function(target, index, cnt) { return (cnt-index-1)*30 } }); anime({ targets: this.DOM.img, duration: 1000, easing: 'easeOutExpo', scale: 0.7 }); anime({ targets: [this.DOM.columns.left, this.DOM.columns.right], duration: 1000, easing: 'easeOutExpo', translateX: function(target, index) { return index === 0 ? -30 : 30; } }); }; HamalFx.prototype._out = function() { var self = this; anime({ targets: this.DOM.stackItems, duration: 500, easing: 'easeOutExpo', translateY: 0, rotate: 0, scale: 1, opacity: function(target, index, cnt) { return index !== cnt - 1 ? 0 : 1 } }); anime({ targets: this.DOM.img, duration: 1000, easing: 'easeOutElastic', scale: 1 }); anime({ targets: [this.DOM.columns.left, this.DOM.columns.right], duration: 500, easing: 'easeOutExpo', translateX: 0 }); };
